Answer:

1.95 miles

Step-by-step explanation:

Monday = 4/10 of a mile

Tuesday = 75/100 of a mile

Wednesday = 8/10 of a mile

What is the total total amount beth ran?

Total miles = 4/10 + 75/100 + 8/10

= (40+75+80) / 100

= 195/100

= 1.95 miles

Total total amount beth ran = 1.95 miles

Which of the following expressions are factors of p(x)=60x4+24x3−45x2−18x?
Whitepunk [10]

The factors are 3x, 4x^2-3 and 5x+2

So, Option B, C and F are correct.

Step-by-step explanation:

We need to find factors of the expression p(x)=60x^4+24x^3-45x^2-18x

Solving the expression: p(x)=60x^4+24x^3-45x^2-18x

Taking 3x common:

p(x)=3x(20x^3+8x^2-15x-6)

Now, factor by grouping, the terms inside the bracket.

p(x)=3x((20x^3+8x^2)+(-15x-6))

p(x)=3x(4x^2(5x+2)-3(5x+2))

p(x)=3x(4x^2-3)(5x+2)

So, the factors are 3x, 4x^2-3 and 5x+2

So, Option B, C and F are correct.

Solve the following equation simultaneously 2a-3b+10=0, 10a+6b=8​
tia_tia [17]

2a -3b +10 =0\\\\10a+ 6b -8 =0\\\\\text{Using cross multiplication method}\\\\\\ \dfrac a{(-3)(-8)  - 6(10)} = \dfrac b{10(10) - 2(-8)} = \dfrac 1{ 2(6) - (-3)(10)}\\\\\\\implies  \dfrac a{24-60} = \dfrac b{100+16} = \dfrac 1{12+30}\\\\\\\\\implies -\dfrac {a}{36} = \dfrac b{116} = \dfrac 1{42}\\\\\\\text{Hence}\\\\a = - \dfrac{36}{42} = -\dfrac 67 \\\\\\ b= \dfrac{116}{42} = \dfrac{58}{21}

Tan^2x+sec^2x=1 for all values of x. <br> true or false?
amid [387]

This is not true.

\tan^2x+\sec^2x=\dfrac{\sin^2x}{\cos^2x}+\dfrac1{\cos^2x}=\dfrac{1-\cos^2x+1}{\cos^2x}=2\sec^2x-1

2\sec^2x-1=1\implies\sec^2x=1\implies\sec x=\pm1\implies x=n\pi

where is n is any integer. So suppose we pick some value of x other than these, say x=\dfrac\pi4. Then

\tan^2\dfrac\pi4+\sec^2\dfrac\pi4=1+2=3\neq1
